The standard solution is for the plugin to publish two Relay blackboard 
objects, where each relay object specifies a remote "target" agent address.

A relay example is included in the Cougaar release, in the "demo-ping.zip". 
The ping demo is discussed in the Cougaar Overview slides:

Plugins should use the blackboard service.  The blackboard translates Relay 
objects into messages and handles the I/O.

See the "demo-ping.zip" and "demo-mandelbrot.zip".  Also see the Main documents at:
